History of the Tineina," are often incomplete, and would 

 cause doubt in many cases, were it not that the larva, mine 

 and food-plant remove all hesitation. Thus, the colour of 

 the cilia of the anterior wings is always given, but the other 

 peculiarities of the cilia are never mentioned. Yet the spe- 

 cies may be divided into two great sections by the cilial 

 markings. For instance, one section has the base of the cilia 

 of the antei'ior wings clothed with broad scales, which are 

 pale at their bases, and dark at their apices, so that the cilia 

 appear to be more or less pale, with dark spots. In genei'al 

 these spots arrange themselves to form several dark lines, 

 intersecting the cilia entirely or partially, especially at the 

 anal ano-le : the outer line is always the most distinctly and 



decidedly expressed, and often it is the only one in which the 

 spots unite to form a distinct line. In some few species 

 (Salicis, Floslactella, Vimineticola), this line is not generally 

 distinct, but the dark ends of the scales project irregularly in 

 the cilia; but in all cases the latter beyond such a line or 

 beyond the dark scales, decidedly and abruptly defined, are 

 paler, generally whitish. In the other section it is true that 

 scales project from the base of the cilia, but they are narrow, 

 very little paler at the base than at the apex, and therefore 

 do not form so sharp and conspicuous a line as in most of the 

 species in the other section. And though in these the tips of 

 the cilia are paler, sometimes even whitish, the colour only 

 becomes gradually lighter, and certainly more from the pale 

 lustre of the tips of the cilia, whilst the latter in certain 

 directions are always distinctly grey. I call the above-men- 

 tioned line the divisional line of the cilia, or, more shortly, 

 the cilial line. Frey likewise does not mention it, but on the 

 other hand Herrich-Schaffer separates on that account 

 Turicella fi'om Titijrella (Basalella, H.-S.), Arciiatellaj 

 Fagelldf Salicis and Floslactella.
